i’d keep the upperbody lifts in and not worry about unloading them. Just be sure that you are atleast 3 days out from your meets for heavy bench. Squats and deadlifts I am not a big fan of because they leave me with a bunch of tightness. I would drop these or do them with MUCH lighter weights if you were to leave them in.
Lifting HEAVY is not really that important in season. Just try to get a moderate amt of stimulation from weights and you should be fine.
